Description
This is a high frequency switching DC converter. This DC converter meets the power supply requirements of different grid standards of 220VDC, 110VDC, 48VDC, and 24VDC respectively. When supplying power in different grid systems, the rated DC output of the module is shown in the parameters. (The rated DC output is the absolute value of the voltage, and the voltage polarity is determined by the connection method.)
The DC converter is designed for the working environment of small and medium-sized communication systems and power systems and is designed in accordance with international standards. It can supply power for various small switching equipment, microwave communication, digital products, optical fiber transmission and other communication equipment.
With this DC converter, the power supply system of communication and power equipment can be easily formed.
The DC converter can generally be used independently, or can be used in parallel freely.
Feature
Advanced double-tube forward switching technology is adopted, and isolation design is adopted between modules to prevent mutual influence between modules.
In the case of N+1 backup, even if one or several modules fail, it will not affect the parallel operation of other modules, and the modules can realize automatic current sharing.
Meet the power supply requirements of 220VDC, 110VDC, 48VDC, 24VDC grid standards. The input voltage range is wide, which is basically suitable for the power supply requirements of various grid systems, and the compatibility is relatively good.
The meter-head module adopts a 3-and-a-half-digit meter display to display the output current and voltage, which is simple and practical.
The module adopts a standard chassis with a width of 19 inches and a height of 2U, which is easy to install.
Wide operating temperature range. The full output power can be output in the temperature range of -10℃～+50℃.
Small size and light weight.
